Oh well, I thought this was the new debug screen. 
It is. And it is telling me a few interesting things. I oopsed and forgot to print the level, though
Did you find a pattern to reproduce this?

[In case you are really interested. That line at the bottom tells me the problem happens in the 'at home' state.
But what's interesting is none of the flags are set. It appears to be a problem just walking back and forth....
Or I didn't dump the right flag. More work needed, I guess....]
